7. Foreword
The protection of workers against work-related sickness, disease and injury forms
part of the historical mandate of the ILO. Disease and injury do not go with the job nor
can poverty justify disregard for workers' safety and health. The ILO's primary goal is
to promote opportunities for women and men to obtain decent and productive work in
conditions of freedom, equity, security and human dignity. We have summarized this
as "decent work". Decent work is safe work. And safe work is also a positive factor for
productivity and economic growth.
Today, technological progress and intense competitive pressures bring rapid
change in working conditions, work processes and organization. Legislation is
essential but insufficient on its own to address these changes or to keep pace with new
hazards and risks. Organizations must also be able to tackle occupational safety and
health challenges continuously and to build effective responses into dynamic
management strategies. These Guidelines on occupational safety and health
management systems will support this effort.
The Guidelines were prepared on the basis of a broad-based approach involving
the ILO and its tripartite constituents and other stakeholders. They have also been
shaped by internationally agreed occupational safety and health principles as defined
in relevant international labour standards. Consequently, they provide a unique and
powerful instrument for the development of a sustainable safety culture within
enterprises and beyond. Workers, organizations, safety and health systems and the
environment all stand to benefit.
The ILO is pleased to have led the exercise of drawing up these Guidelines. I am
confident that they will become an invaluable tool for employers and workers and their
organizations, national institutions and all those who have a role in ensuring that
workplaces are also safe and healthy places.

11. Introduction
The positive impact of introducing occupational safety and health (OSH)
management systems at the organization1
level, both on the reduction of hazards and
risks and on productivity, is now recognized by governments, employers and workers.
These guidelines on OSH management systems have been developed by the
International Labour Organization (ILO) according to internationally agreed principles
defined by the ILO's tripartite constituents. This tripartite approach provides the
strength, flexibility and appropriate basis for the development of a sustainable safety
culture in the organization. The ILO has therefore developed voluntary guidelines on
OSH management systems which reflect ILO values and instruments relevant to the
protection of workers' safety and health.
The practical recommendations of these guidelines are intended for use by all
those who have responsibility for occupational safety and health management. They
are not legally binding and are not intended to replace national laws, regulations or
accepted standards. Their application does not require certification.
The employer is accountable for and has a duty to organize occupational safety
and health. The implementation of an OSH management system is one useful approach
to fulfilling this duty. The ILO has designed these guidelines as a practical tool for
assisting organizations and competent institutions as a means of achieving continual
improvement in OSH performance.

See glossary for definition.

13. 1111 Objectives
1.1. These guidelines should contribute to the protection of workers from hazards
and to the elimination of work-related injuries, ill health, diseases, incidents and deaths.
1.2. At national level, the guidelines should:
(a) be used to establish a national framework for OSH management systems,
preferably supported by national laws and regulations;
(b) provide guidance for the development of voluntary arrangements to strengthen
compliance with regulations and standards leading to continual improvement in
OSH performance; and
(c) provide guidance on the development of both national and tailored guidelines on
OSH management systems to respond appropriately to the real needs of
organizations, according to their size and the nature of their activities.
1.3. At the level of the organization, the guidelines are intended to:
(a) provide guidance regarding the integration of OSH management system elements
in the organization as a component of policy and management arrangements; and
(b) motivate all members of the organization, particularly employers, owners,
managerial staff, workers and their representatives, in applying appropriate OSH
management principles and methods to continually improve OSH performance.

15. 2222 A national framework for occupational safety and
health management systems
2.1. National policy
2.1.1. A competent institution or institutions should be nominated, as
appropriate, to formulate, implement and periodically review a coherent national
policy for the establishment and promotion of OSH management systems in
organizations. This should be done in consultation with the most representative
organizations of employers and workers, and with other bodies as appropriate.
2.1.2. The national policy on OSH management systems should establish general
principles and procedures to:
(a) promote the implementation and integration of OSH management systems as part
of the overall management of an organization;
(b) facilitate and improve voluntary arrangements for the systematic identification,
planning, implementation and improvement of OSH activities at national and
organization levels;
(c) promote the participation of workers and their representatives at organization
level;
(d) implement continual improvement while avoiding unnecessary bureaucracy,
administration and costs;
(e) promote collaborative and support arrangements for OSH management systems at
the organization level by labour inspectorates, occupational safety and health
services and other services, and channel their activities into a consistent
framework for OSH management;
(f) evaluate the effectiveness of the national policy and framework at appropriate
intervals;
(g) evaluate and publicize the effectiveness of OSH management systems and
practice by suitable means; and
(h) ensure that the same level of safety and health requirements applies to contractors
and their workers as to the workers, including temporary workers, employed
directly by the organization.
2.1.3. With a view to ensuring the coherence of the national policy and of
arrangements for its implementation, the competent institution should establish a
national framework for OSH management systems to:
(a) identify and establish the respective functions and responsibilities of the various
institutions called upon to implement the national policy, and make appropriate
arrangements to ensure the necessary coordination between them;
(b) publish and periodically review national guidelines on the voluntary application
and systematic implementation of OSH management systems in organizations;

16. Guidelines on occupational safety and health management systems4
(c) establish criteria, as appropriate, for the designation and respective duties of the
institutions responsible for the preparation and promotion of tailored guidelines
on OSH management systems; and
(d) ensure that guidance is available to employers, workers and their representatives
to take advantage of the national policy.
2.1.4. The competent institution should make arrangements and provide
technically sound guidance to labour inspectorates, OSH services and other public or
private services, agencies and institutions dealing with OSH, including health-care
providers, to encourage and help organizations to implement OSH management
systems.
2.2. National guidelines
2.2.1. National guidelines on the voluntary application and systematic
implementation of OSH management systems should be elaborated based on the model
provided in Chapter 3, taking into consideration national conditions and practice.
2.2.2. There should be consistency between the ILO guidelines, the national
guidelines and the tailored guidelines, with sufficient flexibility to permit direct
application or tailored application at the organization level.
2.3. Tailored guidelines
2.3.1. Tailored guidelines, reflecting the overall objectives of the ILO
guidelines, should contain the generic elements of the national guidelines and should
be designed to reflect the specific conditions and needs of organizations or groups of
organizations, taking into consideration particularly:
(a) their size (large, medium and small) and infrastructure; and
(b) the types of hazards and degree of risks.
2.3.2. The links between the national framework for OSH management systems
(OSH-MS) and its essential elements are illustrated in figure 1.

17. 3333 The occupational safety and health management system in the
organization
Occupational safety and health, including compliance with the OSH requirements
pursuant to national laws and regulations, are the responsibility and duty of the
employer. The employer should show strong leadership and commitment to OSH
activities in the organization, and make appropriate arrangements for the
establishment of an OSH management system. The system should contain the main
elements of policy, organizing, planning and implementation, evaluation and action for
improvement, as shown in figure 2.

Planning and implementation
3.7. Initial review
3.7.1. The organization's existing OSH management system and relevant
arrangements should be evaluated by an initial review, as appropriate. In the case where
no OSH management system exists, or if the organization is newly established, the
initial review should serve as a basis for establishing an OSH management system.
3.7.2. The initial review should be carried out by competent persons, in
consultation with workers and/or their representatives, as appropriate. It should:
(a) identify the current applicable national laws and regulations, national guidelines,
tailored guidelines, voluntary programmes and other requirements to which the
organization subscribes;
(b) identify, anticipate and assess hazards and risks to safety and health arising from
the existing or proposed work environment and work organization; and
(c) determine whether planned or existing controls are adequate to eliminate hazards
or control risks; and
(d) analyse the data provided from workers' health surveillance.
3.7.3. The result of the initial review should:
(a) be documented;
(b) become the basis for making decisions regarding the implementation of the OSH
management system; and
(c) provide a baseline from which continual improvement of the organization's OSH
management system can be measured.
3.8. System planning, development and implementation
3.8.1. The purpose of planning should be to create an OSH management system
that supports:
(a) as the minimum, compliance with national laws and regulations;
(b) the elements of the organization's OSH management system; and
(c) continual improvement in OSH performance.
3.8.2. Arrangements should be made for adequate and appropriate OSH planning,
based on the results of the initial review, subsequent reviews or other available data.
These planning arrangements should contribute to the protection of safety and health at
work, and should include:
Planning &

and clear performance criteria indicating what is to be done by whom and when;
(c) the selection of measurement criteria for confirming that the objectives are
achieved; and
(d) the provision of adequate resources, including human and financial resources and
technical support, as appropriate.
3.8.3. The OSH planning arrangements of the organization should cover the
development and implementation of all the OSH management system elements, as
described in Chapter 3 of these guidelines and illustrated in figure 2.
3.9. Occupational safety and health objectives
3.9.1. Consistent with the OSH policy and based on the initial or subsequent
reviews, measurable OSH objectives should be established, which are:
(a) specific to the organization, and appropriate to and according to its size and nature
of activity;
(b) consistent with the relevant and applicable national laws and regulations, and the
technical and business obligations of the organization with regard to OSH;
(c) focused towards continually improving workers' OSH protection to achieve the

(d) realistic and achievable;
(e) documented, and communicated to all relevant functions and levels of the
organization; and
(f) periodically evaluated and if necessary updated.
3.10. Hazard prevention
3.10.1. Prevention and control measures
3.10.1.1. Hazards and risks to workers' safety and health should be identified and
assessed on an ongoing basis. Preventive and protective measures should be
implemented in the following order of priority:
(a) eliminate the hazard/risk;
(b) control the hazard/risk at source, through the use of engineering controls or
organizational measures;
(c) minimize the hazard/risk by the design of safe work systems, which include
administrative control measures; and
(d) where residual hazards/risks cannot be controlled by collective measures, the
employer should provide for appropriate personal protective equipment, including
clothing, at no cost, and should implement measures to ensure its use and
maintenance.
3.10.1.2. Hazard prevention and control procedures or arrangements should be
established and should:

24. Guidelines on occupational safety and health management systems12
(a) be adapted to the hazards and risks encountered by the organization;
(b) be reviewed and modified if necessary on a regular basis;
(c) comply with national laws and regulations, and reflect good practice; and

organizations, such as labour inspectorates, occupational safety and health
services, and other services as appropriate.
3.10.2. Management of change
3.10.2.1. The impact on OSH of internal changes (such as those in staffing or due
to new processes, working procedures, organizational structures or acquisitions) and of
external changes (for example, as a result of amendments of national laws and
regulations, organizational mergers, and developments in OSH knowledge and
technology) should be evaluated and appropriate preventive steps taken prior to the
introduction of changes.
3.10.2.2. A workplace hazard identification and risk assessment should be carried
out before any modification or introduction of new work methods, materials, processes
or machinery. Such assessment should be done in consultation with and involving
workers and their representatives, and the safety and health committee, where
appropriate.
3.10.2.3. The implementation of a "decision to change" should ensure that all
affected members of the organization are properly informed and trained.
3.10.3. Emergency prevention, preparedness and response
3.10.3.1. Emergency prevention, preparedness and response arrangements should
be established and maintained. These arrangements should identify the potential for
accidents and emergency situations, and address the prevention of OSH risks associated
with them. The arrangements should be made according to the size and nature of activity
of the organization. They should:
(a) ensure that the necessary information, internal communication and coordination are
provided to protect all people in the event of an emergency at the worksite;
(b) provide information to, and communication with, the relevant competent
authorities, and the neighbourhood and emergency response services;
(c) address first-aid and medical assistance, firefighting and evacuation of all people at
the worksite; and
(d) provide relevant information and training to all members of the organization, at all
levels, including regular exercises in emergency prevention, preparedness and

identified prior to the procurement of goods and services; and
(c) arrangements are made to achieve conformance to the requirements prior to their
use.
3.10.5. Contracting
3.10.5.1. Arrangements should be established and maintained for ensuring that the
organization's safety and health requirements, or at least the equivalent, are applied to
contractors and their workers.
3.10.5.2. Arrangements for contractors working on site should:
(a) include OSH criteria in procedures for evaluating and selecting contractors;
(b) establish effective ongoing communication and coordination between appropriate
levels of the organization and the contractor prior to commencing work. This
should include provisions for communicating hazards and the measures to prevent
and control them;
(c) include arrangements for reporting of work-related injuries, ill health, diseases and
incidents among the contractors' workers while performing work for the
organization;
(d) provide relevant workplace safety and health hazard awareness and training to
contractors or their workers prior to commencing work and as work progresses, as
necessary;
(e) regularly monitor OSH performance of contractor activities on site; and
(f) ensure that on-site OSH procedures and arrangements are followed by the
contractor(s).
Evaluation
3.11. Performance monitoring and measurement
3.11.1. Procedures to monitor, measure and record OSH performance on a regular
basis should be developed, established and periodically reviewed. Responsibility,
accountability and authority for monitoring at different levels in the management
structure should be allocated.
3.11.2. The selection of performance indicators should be according to the size
and nature of activity of the organization and the OSH objectives.
Evaluation

26. Guidelines on occupational safety and health management systems14
3.11.3. Both qualitative and quantitative measures appropriate to the needs of the
organization should be considered. These should:
(a) be based on the organization's identified hazards and risks, the commitments in the
OSH policy and the OSH objectives; and
(b) support the organization's evaluation process, including the management review.
3.11.4. Performance monitoring and measurement should:
(a) be used as a means of determining the extent to which OSH policy and objectives
are being implemented and risks are controlled;
(b) include both active and reactive monitoring, and not be based only upon work-
related injury, ill health, disease and incident statistics; and
(c) be recorded.
3.11.5. Monitoring should provide:

Continual improvement: Iterative process of enhancing the OSH management system to achieve
improvements in overall OSH performance.
Contractor: A person or an organization providing services to an employer at the employer's worksite in
accordance with agreed specifications, terms and conditions.
Employer: Any physical or legal person that employs one or more workers.
Hazard: The inherent potential to cause injury or damage to people's health.
Hazard assessment: A systematic evaluation of hazards.
Incident: An unsafe occurrence arising out of or in the course of work where no personal injury is
caused.
Organization: A company, operation, firm, undertaking, establishment, enterprise, institution or
association, or part of it, whether incorporated or not, public or private, that has its own functions
and administration. For organizations with more than one operating unit, a single operating unit
may be defined as an organization.
OSH management system: A set of interrelated or interacting elements to establish OSH policy and
objectives, and to achieve those objectives.
Reactive monitoring: Checks that failures in the hazard and risk prevention and protection control
measures, and the OSH management system, as demonstrated by the occurrence of injuries, ill
health, diseases and incidents, are identified and acted upon.
Risk: A combination of the likelihood of an occurrence of a hazardous event and the severity of injury or
damage to the health of people caused by this event.
Risk assessment: The process of evaluating the risks to safety and health arising from hazards at work.
Safety and health committee: A committee with representation of workers' safety and health
representatives and employers' representatives established and functioning at organization level

Surveillance of the working environment: A generic term which includes the identification and
evaluation of environmental factors that may affect workers' health. It covers assessments of
sanitary and occupational hygiene conditions, factors in the organization of work which may pose
risks to the health of workers, collective and personal protective equipment, exposure of workers to
hazardous agents, and control systems designed to eliminate and reduce them. From the standpoint
of workers' health, the surveillance of the working environment may focus on, but not be limited
to, ergonomics, accident and disease prevention, occupational hygiene in the workplace, work
organization, and psychosocial factors in the workplace.

32. Guidelines on occupational safety and health management systems20
Worker: Any person who performs work, either regularly or temporarily, for an employer.
Workers' health surveillance: A generic term which covers procedures and investigations to assess
workers' health in order to detect and identify any abnormality. The results of surveillance should
be used to protect and promote the health of the individual, collective health at the workplace, and
the health of the exposed working population. Health assessment procedures may include, but are
not limited to, medical examinations, biological monitoring, radiological examinations,
questionnaires or a review of health records.
Workers and their representatives: Where reference is made in these guidelines to workers and their
representatives, the intention is that, where representatives exist, they should be consulted as the
means to achieving appropriate worker participation. In some instances it may be appropriate to
involve all workers and all representatives.
Workers' representative: In accordance with the Workers' Representatives Convention, 1971 (No. 135),
any person who is recognized as such by national law or practice, whether they are:
(a) trade union representatives, namely, representatives designated or elected by trade unions or
by members of such unions; or
(b) elected representatives, namely, representatives who are freely elected by the workers of the
[organization] in accordance with provisions of national laws or regulations or of collective
agreements and whose functions do not include activities which are recognized as the
exclusive prerogative of trade unions in the country concerned.
Workers' safety and health representative: Workers' representative elected or appointed in accordance
with national laws, regulations and practice to represent workers' interests in OSH issues at the
workplace.

39. The International Labour Organization
The International Labour Organization was founded in 1919 to promote social justice
and, thereby, to contribute to universal and lasting peace. Its tripartite structure is
unique among agencies affiliated to the United Nations; the ILO's Governing Body
includes representatives of government and of employers' and workers' organizations.
These three constituencies are active participants in regional and other meetings
sponsored by the ILO, as well as in the International Labour Conference – a world
forum which meets annually to discuss social and labour questions.
Over the years, the ILO has issued for adoption by member States a widely respected
code of international labour Conventions and Recommendations on freedom of
association, employment, social policy, conditions of work, social security, industrial
relations and labour administration, among others.
The ILO provides expert advice and technical assistance to member States through a
network of offices and multidisciplinary teams in over 40 countries. This assistance
takes the form of labour rights and industrial relations counselling, employment
promotion, training in small business development, project management, advice on
social security, workplace safety and working conditions, the compiling and
dissemination of labour statistics, and workers' education.
ILO Publications
The International Labour Office is the Organization's secretariat, research body and
publishing house. The Publications Bureau produces and distributes material on major
social and economic trends. It publishes policy studies on issues affecting labour
around the world, reference works, technical guides, research-based books and
monographs, codes of practice on safety and health prepared by experts, and training
and workers' education manuals. It also produces the International Labour Review in
English, French and Spanish, which publishes the results of original research,
perspectives on emerging issues, and book reviews.

40. At the onset of the twenty-first century, a heavy human and
economic toll is still exacted by unsafe and unhealthy working
conditions. The Guidelines call for coherent policies to protect
workers from occupational hazards and risks while improving
productivity. They present practical approaches and tools for
assisting organizations, competent national institutions, employers,
workers and other partners in establishing, implementing and
improving occupational safety and health management systems,
with the aim of reducing work-related injuries, ill health, diseases,
incidents and deaths.
The Guidelines may be applied on two levels – national and
organizational. At the national level, they provide for the
establishment of a national framework for occupational safety and
health (OSH) management systems, preferably supported by
national laws and regulations. They also provide precise
information on developing voluntary arrangements to strengthen
compliance with regulations and standards, which, in turn, lead to
continual improvement of OSH performance.
At the organizational level, the Guidelines encourage the
integration of OSH management system elements as an important
component of overall policy and management arrangements.
Organizations. employers, owners, managerial staff. workers and
their representatives are motivated in applying appropriate OSH
management principles and methods to improve OSH performance.
Employers and competent national institutions are accountable
for and have a duty to organize measures designed to ensure
occupational safety and health. The implementation of these ILO
Guidelines is one useful approach to fulfilling this responsibility.
